TypeScript is the superset of JavaScript. TypeScript Decorators are a feature in TypeScript through which you attach functionalities to various parts of objects and classes, functions, properties and parameters etc.

TypeScript Decorators play an important role in many JavaScript based frameworks and technologies including Angular, React, VueJS and other prominent libraries which support TypeScript. That is why it is a very important part of every programmer’s toolset.

Learning this feature and adding it to your toolset will definitely add to your skill set in different directions including Web APIs, client side programming or server side programming.

Whether you are a beginner level programmer, an intermediate or an expert, this course has something for everyone. Explanations are kept so simple and easy to understand that it is easily understood by all, but without losing any core concepts.

The better approach will be to code in parallel and become hands on with these advanced concepts. That is why I have coded each line right there. And concepts and theories have been discussed in live coding so as not to bore with the static slides and graphics. Instead keeping engaged in coding all the time.
